Final Fantasy Crystal Chronicles game save please help me

I got the R4 english Version 1.18 and it works fine when I started playing the game, but when I tried to save the game an error appears stating " Could not save data. Turn off the power and reinsert the DS Game Card." Can anybody please help me to fix the problem. Thanks ^_^
